Document Type and Number:
WIPO Patent Application WO/2020/170873
Kind Code:
A1
Abstract:
This crane comprises: a hanging tool; a trolley that hangs the hanging tool via a hanging member; a girder that supports the trolley to be transversely movable; a travelling part that travelably supports the girder and has a tire; a displacement detection unit that detects the relative displacement between the girder and a road surface on the basis of an acceleration detected by an acceleration sensor; and a crane control unit that performs controlling to suppress shaking of the hanging tool on the basis of the detection result detected by the displacement detection unit, wherein the displacement detection unit corrects an error of the acceleration sensor generated by an inclination of the girder.
